Method of controlling actuator assembly

Abstract

The present invention provides a method of controlling an actuator assembly for suspension systems. The actuator assembly control method of the present invention is possible to control the actuator assembly according to conditions of vehicle velocity and steering angle or vehicle velocity and steering angular velocity, thus reducing energy consumption, thereby increasing the efficiency of the actuator assembly.

1. A method of controlling an actuator assembly, comprising:
 obtaining both a vehicle velocity and a steering angle; 
 determining whether both the input vehicle velocity and steering angle are in a preset advancing operation or retracting operation range; 
 advancing the actuator assembly when both the vehicle velocity and the steering angle are in the preset advancing operation range; and 
 retracting the actuator assembly when both the vehicle velocity and the steering angle are in the preset retracting operation range, 
 wherein the actuator assembly is set such that an actuator assembly retracting operation speed is slower than an actuator assembly advancing operation speed. 
 
   
   
     2. The method as set forth in  claim 1 , wherein the actuator assembly is set such that the actuator assembly retracting operation speed is maintained at a constant value. 
   
   
     3. The method as set forth in  claim 2 , wherein the obtaining of both the vehicle velocity and the steering angle comprises: obtaining a steering angular velocity of the vehicle, the method further comprising:
 determining whether both the input vehicle velocity and the steering angular velocity are in the preset advancing operation range. 
 
   
   
     4. The method as set forth in  claim 3 , wherein the determination of the vehicle velocity and the steering angle and the determination of the vehicle velocity and the steering angular velocity are performed by an AND logic. 
   
   
     5. The method as set forth in  claim 1 , wherein the obtaining of both the vehicle velocity and the steering angle comprises: obtaining a steering angular velocity of the vehicle, the method further comprising:
 determining whether both the input vehicle velocity and the steering angular velocity are in the preset advancing operation range. 
 
   
   
     6. The method as set forth in  claim 5 , wherein the determination of the vehicle velocity and the steering angle and the determination of the vehicle velocity and the steering angular velocity are performed by an AND logic.
